everything is fine once car warms up after a few minutes.  |
I told someone else on this forum after my smog test about the the OBDII monitors resetting every time you cycle the ignition he said I would have failed the smog test.

Early glitches
True early OBD II systems had some problems. For example, the '95 and '96 Legacy, Impreza and SVX versions may exhibit a "not ready" condition during a state I/M program inspection because they reset their readiness code at each engine shut-down.
To boil it down to essentials, it will illuminate the MIL(malfunction indicator lamp) if a system or component fails or deteriorates to the point where emissions could rise to one and one-half times the Federal Test Procedure standards.
From an emissions standpoint, a misfire is about the most dangerous malfunction blah, blah blah i'm tired of typing.
If you don't bother to use the misfire monitor, your SOL! This is a favorite feature of OBD II you can look at misfire counts by cylinder. etc, etc, etc.
Alan, I would say if your getting no CEL, MIL leave it alone. If it's tripping a code, TITTD< acronym
